The P’ing-p’u Tribe is the general term used to describe all the aborigines living on the plains of Taiwan. Since the early seventeenth century when a multitude of Han people immigrated from the other side of the Taiwan Strait, their spiritual and material civilization had gradually been taken away and replaced. This essay aims to explore the general characteristics of the settlement and architecture of the P’ing-p’u Tribe recorded in historical documents from 17th to 18th centuries, and therefore make up the incompleteness of the history of Taiwanese architecture. (1)The settlements were in small nucleate form; (2)the tribes changed their sites regularly; and (3)their settlements were composed of hunting fields, agricultural fields and an residential area. The house of the P’ing-p’u Tribe have two major forms: the high-platform house in the southern part of the Ta-tu river, and the pile-dwelling in the northern part of the river. It seems that the P’ing-p’u Tribe constructed their dwellings mainly to fulfill material needs. Their dwellings shared three basic principles: the house compound were in organic form; the house platform was built above one meter; and the houses’ longer sides of the walls inclined upward.
